Roland | SH-09


The SH-09's exceptional quality combined with its unique live performance and interfacing features allow it to surpass the capabilities of many larger, more expensive synthesizers.

The VCO section features virtually rigid pitch stability in even the most difficult conditions and produces precise, rich waveforms including: Noise,
Sawtooth, Square and variable Pulse Wave with both LFO and Envelope Modulation options. A Sub Oscillator produces any one of three parallel tones that may be mixed with the VCO at the internal Audio Mixer for thickness and extra flexibility with- out introducing tuning difficulties. Both the VCO and Sub Oscillator may be modulated by the LFO0\ Modulator which includes Square Wave, Delayed Sine Wave or Sample and Hold options.

The VCF section of the SH-09 features the highest quality 24 dB/octave Low Pass Filter available for stability, flexibility and rich, deep tones. The extra flexibility is achieved through the SH-09's modulation options including: a positive or inverted envelope, an envelope follower for processing
external instruments, three LFO modulation options, resonance control that may be pushed into self- oscillation for use as an extra sine wave oscillator, and control of the filter from the Bender section. The VCA may control volume with the Envelope Generator, directly from the Keyboard Gate, or be fully opened with a Hold switch for added flexibility. This control is enhanced by the complete four
slider ADSR Envelope Generator which may be activated by either the Keyboard Trigger and Gate, the Keyboard Gate alone, or by the LFO and the Keyboard Gate together. These options combine with other control possibilities to make the SH-09 an exceptionally sensitive musical instrument. The LFO Modulator control offers Sine Waves with or without delay, Square Waves, Sample & Hold and a separate Sine Wave without delay for the Pulse Width Modulation section. The LFO speed is fully adjustable and indicated by LED for precise, predictable control. The SH-09 Bender section is the finest available. The center sprung lever returns to its origin automatically for quick, easy, musically secure playing. The Bender may control pitch through the VCO or tone through the VCF either separately or simultaneously with amounts preset by the per- former for exact, predictable control of the synthesizer.

Interface options on the SH-09 include industry standard CV and Gate inputs and outputs for connection with Roland digital sequencers, other Roland synthesizers and with any other equipment offering 1 volt per octave Keyboard Control Voltage and positive voltage Keyboard Gate inputs and outputs. Other instruments may be processed through the SH-09 using the self contained External Audio Input with the Envelope Follower contained in the VCF section. The SH-09 is equipped with a 1/4 inch phone jack output for connection with any conventional amplification and with a separate Vi inch stereo phone jack connection for headphone monitoring through self-contained headphone amplifier. A connection
cable is included with options for connection to either a 1/4 inch phone jack socket or any female RCA jack socket

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
